A method for mitigating airborne pathogens from a livestock house is disclosed. In an embodiment, the method comprises using a cross-flow ventilation system, which is fluidly connected to a livestock house and configured to control the air quality and movement by introducing ambient air into at least one air filtration system that is attached to a side wall of the house; conditioning the air in the air filtration system by performing at least one step selected from filtering, cooling, disinfecting, or pressurizing the air; introducing the conditioned air into an air chamber; flowing the conditioned air from the air chamber into the house through at least one ventilation panel to the opposing sidewall with a laminar or substantially laminal flow of air; and removing the air from the house using an exhaust fan attached to a side wall opposite the side wall containing the air filtration system.

Disclosed is an indoor unit for an air conditioner. The indoor unit for the air conditioner according to the present invention includes: a cabinet assembly forming an external appearance of the indoor unit and having an air suction port formed in a rear of the cabinet assembly; a filter module disposed at the air suction port to filter dust contained in air being introduced through the air suction port; a filter cleaner configured to move upward and downward in a rear of the filter module to remove foreign substances stuck in the filter module; a guide rail vertically disposed on one side of the filter module and configured to guide upward and downward movement of the filter cleaner, wherein the filter cleaner comprises: a mobile gear configured to rotate while engaged with the guide rail to move the filter cleaner upward and downward with respect to the filter module, a gear motor configured to rotate the mobile gear, an agitator configured to rotate in friction with the filter module, a dust container disposed downward of the agitator and collecting foreign substances separated from the filter module due to the rotation of the agitator, and a guide roller bringing the filter cleaner into close contact with the filter module so that part of the agitator rotates while in contact with the filter module.

A filter cleaner and an air-processing apparatus including a filter cleaner are provided. The filter cleaner may include a housing that forms an external appearance and having a suction hole formed in a first side thereof and a discharge hole formed in a second side thereof, a moving gear rotatably disposed in the housing and configured to move the housing, a gear motor configured to rotate the moving gear, a dust container disposed so as to be introduced into or withdrawn out of the housing and configured to store foreign substances introduced thereinto through the suction hole and to accommodate an agitator rotatably disposed therein, an agitator gear disposed inside of the housing to rotate the agitator, an agitator motor disposed inside of the housing to operate the agitator gear, and a suctioner disposed inside of the housing to induce air to flow into the dust container through the suction hole.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

The disclosure provides an air purifier. The air purifier includes a shell, a first plasma generator, a filter assembly, a second plasma generator, and a ventilation assembly. An air inlet and an air outlet are formed in the shell. A ventilation channel is formed between the air inlet and the air outlet of the shell. The first plasma generator, the filter assembly, the second plasma generator, and the ventilation assembly are separately arranged in the ventilation channel. In an air outlet direction of the ventilation channel, the first plasma generator is arranged between the air inlet and the filter assembly, and the second plasma generator is arranged between the filter assembly and the air outlet. By adopting the above structure, the first plasma generator is arranged between the air inlet and the filter assembly, and a plasma wall is formed on the periphery of the filter assembly.
